UK safety inspectors check all 52 London theaters

Shocked and injured theatergoers are transported to hospital in a commandeered London bus following an incident during a performance at the Apollo Theatre, in London's Shaftesbury Avenue, Thursday evening, Dec. 19, 2013. It wasn't immediately clear which part of the building had collapsed. The London Fire Brigade said the theatre was almost full, with around 700 people watching the show. A spokesman said it was thought between 20 and 40 people were injured. (AP Photo by Joel Ryan, Invision)Photo by Joel Ryan
